Healthy Aging and Nutrition

Study Notes

Aging and Nutrition

Aging is a natural process that brings about various health changes.
Healthy lifestyle habits, like good nutrition and physical activity, can reduce disease risk and enhance life quality in older adults.

Energy Needs

After age 50, energy needs decrease by approximately 5% per decade.
Decreased metabolism, muscle mass, and physical activity contribute to reduced energy requirements.
Careful meal planning is crucial to meet nutrient needs while consuming fewer calories.

Weight Management

Generally, weight gain should be avoided, but a slight gain may be beneficial for those aged 70-75.
Studies indicate that lower death rates are observed in overweight individuals compared to those classified as obese.
BMI rankings may need adjustment for individuals over 65 to reflect changing health dynamics, though there's no universal standard.

Vitamin D and B12 Considerations

The skin's ability to synthesize vitamin D decreases with age, combined with typically reduced sun exposure among older adults.
Vitamin B12 needs are higher in older adults, although the recommended dietary intake remains unchanged.
The ability to absorb naturally occurring vitamin B12 diminishes with age; thus, synthetic forms of the vitamin are recommended for better absorption.
